Abstract
Method for the controlled pre-rolling of slabs, advantageously thin slabs, leaving a continuous casting plant, whereby the pre-rolling is carried out with pairs of pre-rolling elements (14, 114, 16) such as idler rolls, powered rolls, plates, belts, scrapers or other means assembled in at least one pre-rolling assembly (10), the first of these pre-rolling assemblies (10) being positioned immediately downstream of the foot rolls (12) of a crystalliser (11), all or a part of these pre-rolling elements being associated with at least pressure transducer means (18), hydraulic actuator jack means (17) and position transducer means (24), there being also included means (28) monitoring the liquid core within the slab (20), means (25a) monitoring the temperature in the tundish and means (25b) monitoring the temperature of the slab both as it leaves the crystalliser (11) and when it is inside the pre-rolling unit (10), there also being included means monitoring the para of secondary cooling, and means (26) monitoring the casting speed, all these transducer and/or monitoring means being connected to at least one data processing and controlling unit (21), which governs the positioning and the adjustment of the pre-rolling elements (14, 114, 16), the final pre-rolling zone being pre-defined by a specific pair (No. X) of pre-rolling elements positioned along the path of extraction of the slab (20), the data processing and controlling unit (21) having access to an inner memorised archive where there is a plurality of pre-defined tables or technological cards (27) containing the map of the desired values of reduction in thickness in the pre-rolling step as a function of the working parameters pre-set and/or monitored and/or detected continuously, each significant variation of at least two of these parameters causing a new table or technological card (27) to be selected with a resulting re-definition of the position and/or action of the pre-rolling elements (14, 114, 16). <IMAGE>
